SPECIFICATION forming part of Letters Patent No. 766,369, dated August 2, 1904.

Application filed March 31, 1903.

To (all whmn it may concern:

Be it known that I, CHARLES MnRAwHow vii'ru, a subject of the Emperor of Austria- Hungary, residing at 5 Fecsey-Utcza, Budapest, Austria-Hungary, have invented certain new and useful Improvements in Telegraphic Apparatus, of which the following is a specilication.

This invention has for its object telegraphic apparatus wherein a perforated band is used at the transmitting station for projecting through the line a suitable succession of positive and negative currents serving at the receiving-station to perforate a second continuous band in a manner similar to that in which the first band is perforated. The band thus perforated at the receiving-station may be used afterward in combination with a suitable machine for casting type--for instance, a machine of the Mray and Rozarsystemso that any typographic text can thus be composed directly from a great distance, The chief fea: ture of the invention is a receiving device by means of which a band at the receiving-station can be immediately perforated instead of having registered on it written letters. The said receiving device comprises, essentially, a number of pins or points arranged to perforate a band of paper passing in front of them, electromagnets connected to line, and intermediate devices which under the action of the electromagnets are engaged with a mechanicallyoperated motive device, under the influence of which they first displace the points, or certain of the said points, to a position such that the said points can, independently of the intermediate devices above described, be pushed through the paper band and then withdrawn by means of a motive device having always the same stroke and which is independent of the electromagnets. The mechanical work of the band-perforator is thus quite distinct from the work of the electromagnets, and the latter have only to operate light devices, which are afterward subjected to the mechanical action of the first motive device to cause the engagement of the points with the second motive device. \Vith this arrangement theresistances generated by the mechanical operations in the apparatus do not all operate simultaneously,

but successively, so that the ordinary motive and regulating mechanism can easily overcome the said resistances without any great variations in speed that is to say, without interfering with the synchronism of the transmitting and receiving devices.

There are various mechanical devices for perforating the band of paper in accordance with the novel method above described. For instance, we will describe one form of apparatus which is the result of suitable modifications made in telegraphic apparatus of the well-known Bandot system.

In the accompanying drawings, Figure 1 is a vertical section of the perforator on the line C l) of Fig. 2. Fig. 2 is another vertical section on the line E F of Fig. 1. Fig. 3 is a front elevation of the perforator. Fig. 4 is a partial side elevation.

Referring to the drawings, 7 designates the paper band which is to be perforated at the receiving-station, the perforating mechanism including a series of pins 50, provided with heels 51,a cam 52,designed to actuate these pins through the paper band 7, a back or support 53, and an intermittent feed mechanism for moving the band in front of the pins. These various devices are employed in combination with a system of slides 54:, which I call linders, and an actuating mechanism for the linders similar to that of the Bandot printing apparatus.

\V hen the relay of the telegraphic system in which the invention is used sends a local current into one or more of the electromagnet-s 55, the armature 56 of each of the excited magnets presses upon an arm of a bent lever 57 and causes it to be released from a springstop, so that the other arm of the lever is moved into alinement with the mouth of a cam-groove 59, formed in a rotating disk or wheel. As said disk or wheel rotates, the lever 57, engaged by said cam-groove 59 therein, is forced against the corresponding finder 54, which moves the corresponding pin 50 longitudinally and brings a projection 51 thereon into position to enter a cam-groove 52 formed in a second disk mounted on the same shaft as the one containing the groove 59. As said disks are rotated in the direction of the arrows in Figs. 1 and 2, said projection 51 enters the groove 52, and the pin is thereby reciprocated, its point being forced through the band 7 and then Withdrawn to its original position.

The unexcited electromagnets 55 do not operate their levers 57, which remain in the position shown in Fig. 1, so that the finders 54 and thecorrespond ing pins 50 are not actuated.

It will thus be seen that for each revolution of the cams 52 and 59 a transverse series of perforations is obtained in the band 7 corresponding to the excitations of the electromagnets 55. One of the pins 50 must operate at each rotation of the cam in order to produce in the band the perforations which enable it to be fed. To this end the said pin is always held in contact with the cam 52 by a spring fixed to the frame.

To produce the feed of the band 7, the shaft of the cams 52 and 59 carries a third cam 60, acting upon a lever 61, connected by a link 62 to a lever.63, of which the pawl act-uates a ratchet-lever 64, moving with the spindle of one of the rollers 65 and 66, between which the band passes. The lever 61 is pressed against the cam by the action of a spring 67 but it can be moved away by means of an eccentric 68 when it is desired to interrupt the feed movement of the band 7 In the abovedescribed construction the novel telegraphic apparatus is considered as being the result of a modification and of improvements of the Bandot telegraph. However, it is obvious that the described arrangements can be combined with any other telegraphic apparatus more or less similar without departing from the characters of the present invention.

The above-described arrangements may be modified and replaced by other equivalent ones.

I claim- 1. In a telegraphic apparatus, a perforating device comprising punches, slides engaging said punches, driving-cams adapted to engage respectively the punches and the slides, the slide-cam operating before the punch-cam, the slides being adapted to bring the corresponding punches into position to be engaged by the punch-cam, electromagnets, and means operated by the electromagnets for moving the corresponding slides into position to be engaged by the slide-cam.

2., In a telegraphic apparatus, a perforating device comprising pins, slides adaptedto push the said pins, a driving-shaft, a cam on the on the shaft to act upon the slides, and means for moving the slides into connection with the last-named cam, the said cams being so arranged the one with respect to the other that the slide-cam displaces the slides to push the pins into a connected position before the pincam acts upon the said pins.

In testimony that -I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
